Cover Story: Information entropy concepts become useful in chemistry where chemical objects are representable as mathematical sets or have a probabilistic nature. The idea of the review is to collect under one title key works on the interrelated chemical applications of information entropy. They deal with molecular topology, electronic structure of atoms and molecules, stochastic physical and chemical processes, and signal processing. The cover picture stresses that information entropy could take a central place in interdisciplinary studies on the interface of physical, structural, and digital chemistry. View this paper
